The new cast of Dancing With the Stars hasn't even been announced yet, but there may be one more opening than expected.

People was the first outlet to notice that co-host Brooke Burke Charvet announced her dismissal overnight Friday via Twitter: "Shocking pre-season elimination: Tom Bergeron didn't even read my name. I won't be returning."

In a statement, she said, "I have enjoyed seven seasons co-hosting DWTS but understand the need for change considering the position of the show at this juncture."

The winner of Season 7, Burke-Charvet replaced Samantha Harris as co-host in Season 10.

It's been a year of change for the veteran reality competition, which is about to enter its 18th season. This fall, the Tuesday results show was eliminated, with the ousted contestants receiving their walking papers at the beginning of Monday's episode.
